SPECIFICATION forming part of Letters Patent No. 494,802, dated April 4,1893.

Application filed August 24, 1892. Serial No. 443,989. (No model.)

To caf/ZZ whont it may concern:

Be it known that I, LEVI N. BOREM, a citizen of the United States,residing at Englewood, in the county of Cook and State of Illinois, haveinvented a new and useful Combination- Vise, of which the following is aspecification.

My invention relates to new and useful improvements in vises or clamps,and is especially adapted for use in connection with carpenters benches,or may be attached to such places as are most convenient, whereby thesame may be best used for the purposes hereinafter specified.

The tirst feature of the invention consists essentially in combiningwith two clamping jaws, adapted to receive and hold a board for edgeplaning, or a saw for sharpening, of an adjustable sliding clamping heador bench dog provided with teeth adapted to bind between it and the headof the vise clamp, a board for surface planing.

The second feature of the invention consists in mounting upon the bencha vertically adjustable stop block upon which one end ot' a boardsecured in the vise for edge planing is received and held in position.

The third feature of the invention resides in the peculiar constructionof the vise clamp, whereby adj ustability of the fulcrum for the movableclamping jaw is attained to accommodate differentwidths of board.

Other minor details of invention reside in the peculiar construction,arrangement and combination of parts, all as will be hereinafter morefully described, and afterward pointed out in the claims.

Referring to the drawings, wherein like symbols of reference refer tolike parts wherever they occur: Figure l, is a side elevation of myimproved vise and stop block secured on a bench for convenience ofillustration. Fig. 2, is an end elevation of the same lookingr at thatend to which is attixed device. Fig. 3, is a top plan view. Fig. 4v, isa perspective view of the vise detached showing the clamping jaws in adistended position. Yspective view of the sliding jaw with its adjustable fulcrum bar. Fig. 6, is a perspective view of a pair ofdetachable face plates adapted to be secured on the ends ot therespective clamping jaws when it is desired to clamp a saw forsharpening. Fig. 7, is a per Fig. 5, is a per- In the drawings A,represents a bench of au ordinary or approved construction provided withthe usual legs a. This I have shown for convenience ofillustration, asit is obvious that the detachable vise may be secured to a convenientplace provided with a projecting ledge, as is most desirable to theuser.

B, indicates a fixed head of the vise provided with binding screws orthumb nuts b, on its inner face, which are adapted to impinge againstthe ends ol the side board of the bench. The inner end face of this headI preferably groove, as at b' and place in the bottom thereof anotherbinding screw or thumb nut h2. For this purpose I preferably extend thebottom of' the slot outwardly to form a lug or bearing for the thumbnut.

Projecting laterally from the head is a guide rail C, upon which isslidingly mounted a locking head D, from the inner face of which projectteeth or taperings lugs d, which, act in conjunction with similarlyprojecting teeth b3, on the inner face of the head B, to clamp andretain therein a board for the purpose of surface planing. To rigidlyretain the sliding block D, on the rail C, and clamp the board tightlybetween it and the head B, I provide an impinging binding screw d in thelower face thereof which, impnging against the guide rail C, retains thesliding block D, in its adjusted position.

Secured to the outer end ot the guide rail C, is a clamp E, throughwhich the guide rail passes and is secured. The inner end of this clampis split or bifurcated to afford reception for the projecting ledge ofthe bench, and one end of the bifurcated portion forms a bearing for abinding nut or thumb screw e, which passes therethrough, and impingesagainst the ledge of the table.

F, indicates the movable jaw of the clamp provided at about its centerwith a fulcrnm bar F which is pivoted therein, the free end of which isadapted to pass through an opening b4 in the vise head B. I formadjusting holes f, in the fulcrum bar whereby a pivot pin G, passingthrough the opening b4 in the Ahead may be passed through any one ofthese adjusting holes, thereby enabling the mov- IOO able clamp to beadjusted laterally to accom-- said cam being provided with an actuatingY handle h, the function of which cam being when the fulcrum bar isadjusted to give the clampingjaw the desired width, and the material isin place, the handle h, which, when disengaged, was horizontallydisposed, is elevated, thus thrusting the cam surface h of the cam, intoengagement with the vise head and forcing the upper extremity of themovable clamp F, toward the vise head, and' clamping the material inposition.

I, representsa stop block preferably formed in its upper face with aseries of steps z', to accommodate different Widths of material, and isprovided on its inner face with projecting guide [ianges I which claspsthe T- shaped guide-Way J, detachably secured lto the bench. 4Projectinginwardly from the lower extremity of this guide-way is a semi U-shapedstrap through the end of which passes a binding nut or thumb screwadapted to impinge against the inner side of the side board of thebench, and retain the guide-Way in a vertical position.

To vertically adjust the stop block on the guide-Way I provide the samewith a binding screw K, which impinges against the head of the guide-waythus permitting, when the screw is released, the movability of a stopblock to any position on the way to accommodate different widths ofmaterial relative to the top of the bench.

L, indicates removable face platesconsisting of laterally extending armsZ, a depending body portion Z', and laterally extendinglocking anges Z2,the function of which latter is to .clasp the head and movable clampingjaws of the vise and retain the face plates in position. If desired theinner surface of these desired I may 1 also rigidly secure the faceplates to the jaws of the device permanently instead of having themdetachable, as is herein shown and described.

I am aware that many minor changes in the construction and arrangementof the parts of my device may be made and substituted for those hereinshown and described Without in the least departing from the nature andprinciple of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

1. In a vise, the combination, with the head provided with thumb-nutsand binding screws on its inner faces and a -lug extending outwardlyfrom the bottom of the head and carrying a thumb-screw, of a clampingjaw pivotally secured to the-end of the head, and a locking cam.fulcrumed in the clamping jaw below the fulcru-m bar, substantially asspecifled.

2. In combination with a vise provided with a removable clamping jaw andmeans for locking said jaw imposition, a guide rai-1projectinglaterallyfrom the vise head, a sliding locking head havingtapering lugs projecting from its inner face, and similar teeth on theinner face of the vise-head, substantially as and for the purposesetforth.

3. In combination with a vise provided with a locking jaw and means forlocking said jaw `in position, of alguide rail projecting laterally fromsaid vise', means for attachment on. the end of said locking rail, asliding block mounted on said rail, means for locking said block in an`adjusted position, and teeth or projections on saidblock and vise headabove the rail, substantially as and for the purposes described. Intestimony whereof I affix my signature in presence of two witnesses.
